Be it known that I, RICHARD L. Lion),v citizen `ofthe United States,residing at N ew York, in the countyof New York and State of'N ew York,haveinvented certain new and useful Improvements in Ore-Distribut ingMechanism for Charge Cars, of` which the following is a specification,reference being had .therein to the accompanying drawing. Y p r Thisinvention relates to an apparatus for forming piles orstrata of granularor reduced material which are normally uniform in thickness or verticaldimension but which canbe optionally varied in respect to is especiallydesigned for the handling of oreand the materials used in ore treatment,particularly the mechanism employed for loading the cars which areemployed to carry charges of the component materials thatare introducedinto blast furnaces.

Fig. 5 is a plan view of the distributor shown in Fig. 4.

Fig. (3 is a View similar to Fig. 3, but showing the modificationillustrated in Fi .4.

Figf shows in top View and in section a part of a modified formofcarrier apron.

The framework supporting the apparatus comprises the bars 1 and 2,' `theuprights 3,

and suitable cross bars or bracesv as at 4, these being preferablyformed of sheet yor angle or channel metal- The channel bars 1 extendacross a depressed. 'runway 5, in which are laid rails 6, 6 forsupporting and `guiding the charge car 7. The loading'or chargingelement comprises the car 8 provided With axles 10 on which are mountedwheels 9.

, l1, 1l8L are shafts yin bearings 12 secured to the upper faces of theside bars 8a ofthe i920. Serial No. -3,731; "z

drum 13, 13, rigidly .secured therct'o,'thev drums being positionedequi-distant from the sidesof the car. .8.. 14, 14a are ratchet wheelsalso rigidly securedtofthe shafts 11, 11a. 15,15." are dogs adapted toengage with the ratchets. therdogs 'of the front'pair being pirotallysecured to mounting 16y on the sidebars 8a, ,and those ofthe rear pairbeing mounted l on pinions 17 pivotally mounted on the rear shaft 11n. ff i' 18 is a belt or endless apron on the fdrums 13, 13a. It may bemadeof any suitable material for carrying the ore which is to bev depositedin the charge car.. `The upperrun ported uponsmall rollers26, 26,mounted in bearings on side .harsg27, positioned longitudinally andfastened to the tops` of the channel bars-8a.`

Onv .the cross bars 4 are placed longitn dinalchannel irons 19 of thesame length as the c hannelsl and 2.. On the bottom faces of thechannels 19 respectively are secured racks 20, each adapted to engagewith one of the pinions 17 on :the rear'axle 11". 21 isa pneumatic orhydraulic Icylinder in which `isfitted a, plunger connectcdby a rod 22to the rear end .bar 8b of the car 8 `for moving it forward and backwardover the runway 5 as desired.

23 is avhopper in which. the material is initially placed which is to bedeposited in the charger-ar. This hopper is supported at the top by thechannel irons 2, 2, and it which is open. Thebottom edge. ofthe forwardwall .is cut tapers toward its lowerfend,

agent, .oil orwater, is introduced `at the outer end'of the cylinder 21,its lintiow and escape being` controlled by' three-Way `valve at 2l"L orother suitable control device. The plunger advances and pushesforwardthe hopper 23 and" settles upon gate 25, as descri The forwardadvan'ce.of the ca r and forward end part of the latter reaches the verticalplanes ofthe outer side ofthe c lof :the outer edge c 15 engage -withtheratchets 14 and thus pre.-y vent' the apron or lbeltfrom moving backtheycarryingthe dogs lffloosely nary .would the car, because of theresistance tofthe for# v ward movement of the toprun or section ofcharge .car 7 or reaches the vertical lines ,of the stratum or pile tobe formed, during which movement the dogs wardat the top. The a ronlunder ordicircumstances, an tend' to move backward, relatively to thebelt causedby the heavy'material flowingA from the hopper. Thepinions17, however, are free to rotate `on the shafts 11 in a'counterclockwise; cli-- lre'ction and while .the car is moving forward thesepinions are caused 'to loosely rotate, around, that is out of engagementwith, the teeth of the lratchet wheelsll.

When the car' has reached the position lindicated by dotted lines inFig. 1, the movement of the plunger yand the rod 22 in the cylinder 2lvis reversed, the operator, by the necessary valves, reversing the,intakev and exhaust of vthe Huid agent; and the car orV distributin toits original position. Now the pinlons' element 8 is. drawn backward 17byA engagementffwlth the. ratchet 20 are `causedto -rotate in aclockwisevdirection, and

the'dogs 15'3L on therear axle 11a engage with the' ratchet wheels Maandcause them to rotate the drums.I 13--j13i land-to relatively movethe-apron forward. This causes the material of the stratum on the apronor beltA to be distributed over vand dropped from the front roller 13'and deposited inthe 'car 7 or on any preferred support. :As-theoperative .parts act automatically a uniform-.stratum is deposited whichis normally exactly simi' lar in Aits dimensions tothe stratum formed onthe apron or belt." Y If it bedesired to deposit another. stratum ofdimensions equal to that described above, the gate25 is allowed toremain in the position which it v has been occupying and the movementsof the car 8 are repeated. If it be desired to form a .layer which -isof greater or lessvertical dimension than that of a previously formedstratum, ther` gate 25 is adjusted correspondingly and then the `car ismoved in themanner above described; If it be 'necessary to form inthecar 7 a stratum which in one region is of greater depth than inanother,

i this is attained bycontrolling the movements of the plunger 22 in sucha way as to cause the delivery end of the apronto reapron is continueduntil the unless' locked wensen ciprocate "overishorterfor longersections of lthe total pathfotthedistributor. Or use lmaybe made of' :aipower-device or motor,

supplemental those. .above referred to, by which the forward roller 13can be rotated at will even while itsI supportingcar is relativelystationary.

I'f it be vdesired .to-pfor'mstrata, in the charge car, each composed ofdifferent material, for example, one being composed of ore and theothei'srespectively composed of l'the heat generating and the.flux-'forming ingredients, `supplei'nental sets of devices `similar tothose described can'be provided Iby' duplicating the mechanismsh'own,each hopper to be' supplied with one yof the vari- 'ousmaterials j `Insuch casezthe charge car, after receiving one or more strata ofthematerialv inthe first/hopper, can be advanced to the' second to receivea proportionate quantity throughout they series.

In Figs. 4, 5 and 6 fied mechanism toserve as the stratum forming landdistributing element. The car .8", here', is s o constructed that theupper run or section of thedistributing apron is considerably lowerrelatively and the several parts'are `more compactly arranged. TheA sidebars 8fl of the car- 8c have the portions of a second material, and soon I have Ashown a modibetween the axles drooped down as in Fig.

4. A strong durablestratum' support 18a. is vformed of metallic carriersections 18b (Fig. 7 fitted to chains 18c positioned along the sides.The floor parts of the sections overlap, eachthe next, andprovide acontinuous floor vsupport for the ore orother material. This carrier issupported on vdrums 13",'1Sc having ratchets and dogs.- [The latter,however, differ 'from those in the construction in Figs. l, 2 and 3 inthat those connected to the rear drum are mounted and operate in .a waylsimilar'to that in 'which the Aforward ratchets are mounted andoperated;

f A simple device for'ei'ecting' a movement of the sectional apron 18biscombined with it; the same consisting of dogs 50 supported Yby pivots onthe hopper 23, there being one of ,these in the vertical longitudinalplane of eachv of the chains 18. When the apron inthe mechanism in Fig.4 is movedy forward with the ca-r 8", it is bodily stationary on the'caras dogs 15h engage the ratchets and prevent'any backward movement oftheupper run. During such forwardr movement of the car 8c`the dogs 50vibrate idlyfvertically as. the chain links move under them. But whenthe car 8c is drawn backward again by the plunger, the lower end of eachdog 50 engages with the ends of the link bars or with the cross bars orpintles of the links of its chain and the chains 18c and the metal apron18b are held4 stationary relative to the hopper; but are moved,relatively,'varound the rollers." therefore the material ofthe stratum,which was deposited on the metal apron duringy the vforward,

movement of the car 8, is now dropped over the `forward, receiving, endof the distributor and a oorrespondlng stratum. is

v formed below it, as in car 7, in the manner above described. j y Y vThe apparatus in these Figs. 4, 5 Vand 6 comprises a supplemental motor31, such as was above referred to. It is mounted on a lplatform '31secured rigidly to the car 8c in another, the vmovement bodily, of thecar 8 is stopped, and the motor 31 is put into action; Thereupon thestratum supporting apron moves around its drums'and continuesv to.deliver material until the motor is again vsto ped.

hile I have above described somewhat in detail devices which can beemployed to carry out my invention itis to be noted that,

v modification can be made ,with-outdeparting from the spirit thereof.It will be seen that` the charge car at 7 is to be'regarded as ,typicalof final supportsv of predetermined areas upon which the strata are to'be formed.; and also that each operativesection of the endless apron canbe consideradas an initial v support for the stratum, which lattersupport togetherLwith the stratum are movable bodily in one directionover` ,the aforesaid final area, and furtherthat'theinitial supf port ismovable bodily in the opposite direction and is also relatively movableso as to deliver the stratum to the car/6r final su port. The car-8serves as a carrier for t e initial support, which as eze/mplified hereis an endless apron that moves bodily with the carrier when the latter,is moving inone direction, and moves both bodily -with and in relationlto the carrier rwhen the latter is moving in the opposite direction;
